IMPROVEMENT IN HORSE-POWERS.

Specification forming part of Letters Patent No. 48,600, dated July 4, 1865.

cured together in a triangular form, as shown in Figure 2.

E and F represent two triangular metallic A ,bed-plates, which are secured to the frame A, one on the upper side of said frame and the other on the lower side. The bed-plates are seen in dotted line, Fig. 2.

C represents the mastcnwheel ofthe machine, which is cast with an arm projecting from the center of its under side, which acts as an axis for the wheel to revolve around.

a, Fig. 1, represents this arm, which extends down through proper openings to receive it in the bed-plates E and F, and is secured in this position by means ofapin,which passes through it beneath the plate E. Upon the under side of the wheel C, near its periphery, are inserted a series of pins'` provided with small frictionrollers. These pins are placed equidistant on the wheel, and with the rollers work in be tween spiralthreads upon ashaft, D, and give said shaft rotary motion.

c c represent the pins, and d d the frictionrollers on said pins.

The shaft D is secured to one of the pieces of the frame A, lying parallel with and close to it. Said shaft is provided with suitable bearings, which are secured fast to the frame-piece. This shaft D conveys power from the masterwheel C to whatever machine the power is designed to run.

Although only one shaft for driving machinery is here shown, it is evident that three may be used, one on each side, and secured to each of the pieces of the triangular frame. The object of making this frame in a triangular form is more particularly for the purpose-ofrun ning three machines from one power when it is desired. The triangular frame gives more strength at less cost, and more capacity with the same strength and cost, than can be obtained other# wise.

Having thus fully described [ny-invention,

what I claim as new, and desire to secure by J .i B. SWEETLAND.
